Abstract: The present invention provides methods for preventing the adverse effects of transfusing a patient with blood or blood products compromised by storage lesion. The methods include administering to a patient a pharmaceutical composition comprising an effective amount of a polyoxyethylene/polyoxypropylene copolymer and a pharmaceutically acceptable carrier. The safety and effectiveness of transfusing blood with storage lesion can be increased using the methods of the invention.

Abstract: Methods are provided for the treatment of chronic microvascular diseases characterized by inflammation, such as age-related macular degeneration, by administering a polyoxyethylene/polyoxypropylene copolymer. Although a single dose can be effective, multiple treatments can be administered to achieve an optimal and sustained effect. Preferably, a single administration followed by repeated weekly administration of the pharmaceutical composition, but not continuous infusion, achieves a desired effect. Methods of diagnosis and characterization of chronic microvascular diseases using the copolymer are also provided.

Abstract: The present invention relates to compositions and methods for delivery of antisense oligonucleotides or other nucleic acid sequences. The present invention comprises a delivery composition comprising an administerable admixture of an effective amount of a nucleic acid sequence and an effective amount of a surface active nonionic block copolymer having the following general formula: HO(C2H4O)b(C3H6O)a(C2H4O)bH wherein a is an integer such that the hydrophobe represented by (C3H6O) has a molecular weight between approximately 750 and approximately 15,000, preferably between approximately 2250 and approximately 15,000, more preferably between approximately 3250 and approximately 15,000, and b is an integer such that the hydrophile portion represented by (C2H4O) constitutes approximately 1% to approximately 50% by weight of the compound, preferably approximately 5% to approximately 25%.

Abstract: The present invention comprises novel polyoxyethylene/polyoxypropylene block copolymers compositions and compounds. The compositions comprise block copolymers that are useful in gene therapy methods.

Abstract: The present invention relates to compositions and methods for treating infectious diseases and genetic disorders through gene therapy and intracellular delivery of antisense oligonucleotides or other nucleic acid sequences. In particular, compositions and methods using biologically active nononic reverse block copolymers are described. The reverse copolymers have an inner core of polyoxyethylene (POE) that is flanked on either end by polyoxpropylene (POP). The reverse block copolymers have the following formula: wherein “b” represents a number such that the molecular weight of the hydrophobe (C3H6O)b is between approximately 750 and 20,000 Daltons and “a” represents a number such that the percentage of hydrophile (C2H4O)a is between approximately 1% and 90% of the weight of the block copolymer.

Abstract: The present invention comprises novel preparations of polyoxypropylene/polyoxyethylene copolymers which retain the therapeutic activity of the commercial preparations, but are substantially free from the undesirable effects which are inherent in the prior art preparations. Because the preparations of polyoxypropylene/polyoxyethylene copolymers which comprise the present invention are a less polydisperse population of molecules than the prior art polyoxypropylene/polyoxyethylene copolymers, the biological activity of the copolymers is better defined and more predictable.

Abstract: The present invention includes novel polyoxyethylene/polyoxypropylene block copolymers as well as methods for making the block copolymers. The block copolymers are high molecular weight molecules and are useful as general surfactants and display enhanced biological efficacy as vaccine adjuvants.
